- Which are the three main types of cost estimations regarding building costs in connection with traditional procurement?
- Pre-tender estimations
- Bid estimate
- Detailed construction estimate
- Give three examples as regards pre-tender estimations

- What is a “conceptual estimate”? Give some example as how it can be expressed!
It is based on early concepts about the project. Often rather general proposals. They can be expressed in quantitaive terms:
• A school building- no of students
• A hospital- no of beds
- The reference data that can be used in connection with pre-tender estimates depending on many
conditions! Name these!
- Type of contractual arrangement/procurement method
- Location
- Type of building – number of buildings
- Size of building
- Geometry
- Standard- chosen materials
- Situatuin on the buildning market
- Which is the main difference between a direct cost and an indirect cost?
Direct costs: can be directly related to a specific part
Indrirect costs: can not be directly related to specific parts- they havet o be divided on different parts according to some principle
Give for a construction project, some examples regarding direct costs and indirect costs
Materials Direct cost Indirect costs
Form, reinfrocment Water at site
Labour Work with reinforcment and form Supervision at sight
Other Painting by sub-contractor Sheds,store at site
- How is the concept operation time defined?
”method time”- the real ”productive time related to the applied method
Additional time: such as waiting for materials, visisting toilet also including ”un-normal” interruptions
Name at least six important factors that are affecting the operation time on a construction site!
- Planning and preparation
- Disturbances
- Climate
- Organisation
- Materials used
- Equipment
- Crew
- Site
- Learning effect
- Explain the concept “learning effect”?
When the same working operation is repeated a reduction in the time-consumption is often registered
- The “learning effect” can be divided into two phases. Which?
learning and improvement
- How is a “learning effect factor” defined according to Wright?
When the number of the produced units doubled, the accumulated average value will be reducedwith specific precentage. If the average value is reduced with p %
- Name some important within construction that affects the “learning effect factor”.
- Type of work/complexity of work
- Number of operations included
- Size of time
- The experience of the team-members
- The level of planning and preparation of the work
